Patented Aug. 7, 1934 UNITED STATES PATENT osmos- This invention relates to imptovements locomotive tender construction and has for its principal object the provision of e'fl'icient means for urging i'ue'l from the rear slope sheet or the fuel I bunker onto the shovelli'ng platform.

A further object of this invention is to equip locomotive tenders with a plurality oi conveyorswhichi a-re mounted on the rear slop'e' sheet of the fuel bin, the conveyors being arranged in spaced 16 relationtransversely of" therear slope sheet and each being independently operated. V

A stillfurther' object or the invention is the provision of means for urging fuel from the rear' slope sheet; of the fuel bunker onto the shovellfng '15 platform of the tender, such means comprising annexed specification accompanying the draw ing, in which Fig. I is a, central vertical longitudinal s'ectio'fi through the forward portion of the improved tender? a 33 Fig. 2 is a: section takenon the line 2-2 of Figure 1;

Fig. 3- is a section taken on: the line of- Figure l with some parts in elevation, and

Fig. is a; section taken on the line H oz 85 Figure 2.

0n the drawing, the locomotive tender is my noted at and comprises a; tank 10 on the Base frame II. The tank 10 consists or a water compartment or ci'ste'rr'i I2 and s-fuei 5m- 16 13 which" is separated from the cistemby side slope sheets 14, 1 5; a rear slope sheet I6 and at floor 17', the forward portion" 18 of which forms the fuel" shovellihg' platform. The usual coal gate f9 is mounted Between the bulkheads 20,- 21" above the 11001-17 a'n'cf may be opened in' any suitable degree to permit coal to fan: onto the shovelli'ng platform" 18'. I

Usually; the fuel bin I3'is'ofsuch length, or the rear sheet 16 is inclined at such agradual slope,

that the entire coal supply is-not'witl'iin con've'm ient reach of the fireman when the fuel bin ispa'r tly' depleted; In order to deliver such coal onto the shoveiling platform which coal does not fall" by gravity" thereon, I n i'o'uht a; plurality of screw conveyors such as 22, 23' and 24 on the rear slope sheet 16. These screw conveyors are spacedtransversely o: the rear slope sheet and at their upper ends are. journalled a;- bearing such as 25".

V The Screw conveyors 2's and 2 s are each 69 driven from; their forward end by suitable snism encased intl'ie housing" so which is dis" posed: iiiar'iai'cove 2'; located amthe forward end of thetencfer beneatl'i'the shovelling platform It? and separated from the water compartment by 6& the usual-partition plates; Fo'rffied withthe housing 26 are the bearings 28, 29 and 30" which form iomna-ls for the shafts 31, 3'2 and as re: spectiv ei'y; These bearings extend through open-- ings at 1:70; in the floor 1:7. The screw com veyors' 22,. 23 and 24 are each in driving engage ment with their respective shafts 31, 32 or 33, and are enlarged m diameter adjacent these bezir- Gi'df't facilitate the passage of cool moreover. From-their" enlarged lower ends; the" conveyor! screws taper upwardly, and at their lower ends the impelling faces of the screw conveyors extend across the width of the fuel hmn-oor whereby cost may be advanced across the entire width oi the shown-mg platform. me so" shafts" 3T,- 32 and 33 ar'e housed the hou's ing 26 arid are not? ioumslled in the W511? 26a! but terminate some distance short thereof.- Shafts such as" 3m; 3222 5nd swore each journalled in the wall 26a and have their axes alignment 3s with the shfiifis" 31;, 32* and 33' respectively.

of these shafts, such as 32a, has connected theseto' a universal joirit' 34 which transmits power from any suitable source through the shaft 35 for driving"- the 22*, 23 and-24- in a manner 96? which: wil-l now be described,

1 On sad; the shafts 31w, 32aand 33a; inter meshing gears such as 36, 37 and 38 are securely aiideoh oi these gears is provided with a; element such as 39. Reafward of these is outmelcments a; slidable' clutch 40- is moimtecloI-i ea'clt shat-t 3%, 32 and 33 and is ar-" ranged to lie-slid intdanu out of engagement with its clutol 'telement 39; Each of the slidable clutches 40 is keyed to its respective 1'60 shaift, and thus whem they are caused toerigaage than res ective clutch. element 39, motion be transmitted to the screw conveyors.

clutch with the clutch element 39. Similarly,

the levers and 46 are mounted on thehollowed shafts 51 and 52 respectively, each of which is mounted over the shaft 47, the .hollowed shaft 51 is apertured as at 53 to allow for'movement of the arm 49. Each of the'shafts 51 and 52 is provided with an arm 54 and 55 for operating the shifting yokes 42 and 43 respectively, through the medium of connecting links similar ;to the-one shown at 50 in connection with the operation of the yoke 41-, a Q

Whenever the fireman has used all of'the coal which is within convenient reach, he then places ,the hand levers 44, 45 and 46 in a position to cause the slidable clutch 40 to engage the clutch element 39 of the gears '36, 3'7- and 38. He then applies power to and 24 will then urge the coal forwardly onto the shovelling platform, 18, .and when a sufficient amount has been delivered, the power to the shaft 35 is stopped and the hand levers 44,-.45

and 46 are moved to their normalpositioni Wheneverit is desired to move coal from aselected portion of the fuel bin, the screw conveyor in that particular portion may bev operated in-' dependently of the other, screw conveyors by moving the proper hand lever.. I

From the foregoing, itwill be apparent that I have constructed a. novelfuel conveyor for use in connection with locomotive tenders..;'1he use:

of this construction is especially adaptable in such;

instances'where the rear slope sheet is pitchedj ata very moderate angle andv is of such length that the use of the ordinary coal pusher of the reciprocating type wouldnot be advantageous be causeiof the long strokewhich the reciprocating engine-would have to makein order to deliver coal onto theshovelling platform; Having described myinvention, I ;now make claimto the followingas new and useful in the I formed therewith, a shaft for each of said screw: conveyors, said shafts journalled in their reparticular art to which this invention relates.
